Start by soaking the rocks to be cut in water for a day. This allows
water to fill the microscopic cracks so that oil can't seep into them
during cutting, thus reducing the cleanup effort.

After cutting many people recommend burying the cut slabs in cat litter
overnight as it extracts most of the oil. Be warned that some light oils
(and vegetable oils) can spontaneously combust in cat litter.  Others
recommend soaking in detergent overnight to remove most of the oil.

You may still have to do some scrubbing by hand with soapy water and a

And if its only one or two items, and you can't wait, I've found that
washing them between your hands with Lava bar soap  (using the bar as a
scrubber, and fingers for rubbing) usually gets them clean in a few

Have been inTucson now since Tuesday.  The rough I have seen has been
very limited.  I decided that if if was not absolutely gorgeous and half
the price of what the cut stones would cost or below I am going to stay
away.  So unfortunately there has not been much.  Please email me if you
are aware of anyone here with premium rough at a true wholesale price. 
I have seen some nice garnet from Tanzania, Mint Grossular Garnet,
Chrome Tourmaline, Big Zircons of various colors, and of course all of
the Pakistani/Afghani Tourmaline (which is always way overpriced). 
Really looking for some premium chunky Aqua.  Let me know how everyone
else has faired so far.  Tyler Atl., GA t.allen@mindspring.com

In reference to cleaning slabs, I have a styrofoam cooler below my slab saw filled
with (clean) kitty litter.  This absorbs the oil and mess, from there, when ready,
I soak my slabs in alcohol to remove remaining oil and let them air dry.

Hi:  A friend gave me a cross section of purple sapphire crystal to cab.  This
should produce a cab in excess of 15mm.  In order for it to 'star' I will have to
remove a lot of material in order to keep  the hex centered and perpendicular to
itself.  This will give me a nice star sapphire but only in the 8mm range.
Being new to lapidary I need adivce to this dilema - Do I go after size and weight,
or sacrifice in hopes for a good star?
Thanks, Dave

In past  I use kerosene and non detergent oil in my rock saws.  I always
seem to get good service out of this combination.

Due to enviremental concerns I am trying a Shell water soluable oil in
my Trim saws.  I noticed last night that the .006 blade in my facters
trim saw  began to wobble and was hard to get it to start a cut close to
the right place on the Stone.   I have been told by a local that  water  

Soluable  oil cools but does not lubricate.  Does anyone have an answer
to this?

It`s true, water coolants do not lubracate at all,i.e less life of saw
blade. We use diesel in place of kerosene and water coolant.

I'm new to cutting slabs and geodes on my lapidary saw. What are your
best suggestions for cleaning the pella oil off of the slabs and geode
halves after they are cut. It is taking me forever to get the oil off.
Any help would be greatly appreciated.

The best way is drop it in to water as u cut it, or you can use some
solvent later to clean it

Wash 'em in dish detergent and water, then bury them in kitty litter for a
while - you can also use the industrial stuff for cleaning oil spills off
floors, but it's basically just.....kitty litter.

Subject: Silver hardening
SIlver softens when heated. Metals, often react differently when
heated, so what works with one, may not with another. Silver
hardens/tempers when worked IE: Drawn, bent/twisted or hammered. If you
hammer it lightly with a planishing hammer(or work it), It will temper.
If you hammer too much it will become brittle, so it may need to be
annealed before continuing to work with it. This last process is used
for prolonged silver working. Silver jewelry, over time, very often;
work hardens from daily banging around. When constructing a ring, I
would often size a ring down one size, put it on a mandrel, hammer it
( Turning it upside down occasionally to keep it from becoming cone
like), just to put some temper in it. Gold and Copper are much the same.
Be very careful with White Gold and Platinum and it's alloys as they're
temperamental in a variety of ways. After hammering is complete, if a
smooth finish is desired; clean the hammer marks off with the necessary
files, sanding and polishing.  I would suggest mastering Silver and
Yellow Gold before taking on the later.

HEAT HARDENING: "After all soldering is done, heat to 536 F and hold
for 2.5 hours. Quench in pickle and finish as usual." (do this after all
soldering is done)

I have used these oils in the past as coolant and lubricant when turning
metals on a lathe. The oil is a lubricant and mixed with water aids in
cooling the workpiece. I suspect that pure oil is better for cutting

From: "Harv Turner" <olharv1@cox.net>

I have found that the easiest way to clean saw oil from slabs is to use
a spray of "Simple Green" directly on the piece then dropping it into a
bucket of detergent and water for an hour or so; rinse and you're done.
Iff you're in a hurry, just spray with the "SG", brush and rinse. I use
what looks like a "toothbrush on steroids" with black fairly soft
bristles, but a toothbrush works well too.
Re: Saw oil vs. water soluable cutting solution... I use both with
success. For serious cutting there is no substitute for a good oil, such
as Pella or, my favorite,  mineral oil. The water-soluable lubricant is
perfectly acceptable for your trim saw and will lubricate the cutting
while it cools and flushes the kerf  from the cut. It will not do
anything to lubricate the saw's bearings and you will be well advised to
perform routine maintenance on the arbor bearings using a moisture
displacement substance such as WD-40 followed by a good light lubricant
such as white lithium grease. WD-40 is not really a lubricant but will
chase the water out so that the lubricant can get to the metal surfaces.
I use a one-step greasless lubricant spray called "LPS" which chases the
water and lubricates in one step. Hope this helps.

Greetings faceters...

In this day of information overload, I don't disseminate advertising,
unless it's a great deal in quality, price, and service.

I got word from the west coast CA, OR, and WA faceters that they are
using diamond products (bort powder, compound, maybe spray too) with
excellent recommendations, from Roy James of BetaDiamond in CA. Since
they consume large amounts of diamond with their extensive membership,
they get a good price discount, and buy in 25ct increments.

BetaDiamond has offered me a somewhat similar pricing deal on what would
be my largest buying order; a mix of 5 different bort sizes in 10ct
quantities, of which I thank you for Roy. With such an agreeable party to
work with,  I want to advise you all of this source.

If you go to:


you will pull up an inquiry page, from which Roy will respond. However,
if you have a similar order such as mine below, with at least these
quantities, feel free to order directly. If less, contact Roy for pricing

We need to support good suppliers, offering well spec'd and good quality
control bort at $1/ct. With ever tightening club and personal budgets,
this is an excellent supplier.

Best regards.....
Phil in Florida
